MACHINE FOR GRUBBING SAGE-BRUSH,

SPECIFICATION forming part of Letters Patent No. 741,979, dated October 20, 1903. Application filed May 8, 1903. Serial No. 156,184. (No model.)

To all whom it may con/cern:

Be it known that I, ANDY ROWAN, a citizen of the United States of America, and a resi` dent of Steamboat Springs, in the county of Routt and State of Colorado, have invented certain new and useful Improvements in Machines for Grubbin g Sage-Brush, of which the following is a specification.

This invention relates to certain new and useful improvements in machines for grubbing sagebrush; and it has for its objects, among others, to provide a simple and cheap machine adapted for .raking sage-brush or any other brush either `before or after the ground is plowed and also one that is adapted to take the place of the harrow to cultivate I also provide a seeder attachment operatively connected with the hindwheel, so as to be actuated wheel. l

A further object is to provide a strong and cheap and efficient rakein which the parts shall be so assembled and held in position as to prevent breakage, suitable Vmeans being provided for dumping the rake at predetermined intervals or whenever it may be desired.

I aim, further, at improvements in the details of construction whereby -a strong and durable machine is provided and the cost of manufacture reduced.

Other objects and advantages of the invention will hereinafter appear, and the `novel features thereof will be particularly pointed out in the appended claims.

The invention is clearly illustrated in the accompanying drawings, which, with the numerals of reference thereon, form a part of this specification, and in which Figure 1 is a plan-view showing a machine constructed in accordance with my invention. Fig. 2 is a side elevation thereof. Fig. 3 is a vertical cross-section on the line 3 3 of Fig.`

1. Fig. 4 is a section at right angles to Fig. 3, the section being taken on the line 4 4 of Fig. 3. Fig. 5 is a section on the line 5 5 of Fig. 1. Fig. 6 is a section on the line 6 6 of Fig. l.

Like numerals of reference indicate like parts throughout the several views.

Referring now to the details of the drawings, l designates the forward axle, 2 the by the rotation of such in Fig. 1.

wheels, and 3 the tongue or bolt of a wagon, which parts may be of any well-known form 4of construction and the wheels of any approved type. As these parts form no part of this invention except to show the application thereof, a detailed description thereof is not given.

My improvement is applicable to any form of wagon, and it is intended to manufacture the same and'place it upon the market ready to be thus applied. E

The present improvementcomprises a metallic frame 4, the same c`onssting, essentially, of two dat pieces of metal bent toform the side bars and the front cross-bar, the ends of said pieces of metal being extended fora ward and substantially parallel with each other, as seen at 5, and secured in any suitable manner, as at 6, to the under side of the short reach or coupling bar 7. The rear por tion of these side bars is twisted,as at 8, to form the rearward extensions 9, which are disposed edgewise and the extreme ends bent inward at right angles to their length, as seen at 10 11 is a cross-bar rigidly uniting the side bars near the bends or twists therein, as seen best in Fig. 1, and 12 is another cross-bar parallel with the bar 11 and secured -to the portions 10 by suitable means, as bolts or rivets 13. (Seen also in Fig. 1.) 14 represents rods having their ends connected to the said bars 11 and 12, as shown, being disposed at right angles thereto or lengthwise of the machine and serving a function which will soon be explained. The side bars of this frame have secured thereto the clamps or bearings 15 for the spindles or axle-skeins ,16, which are preferably integral with the rectangular axle 17, as seen best in Fig. 3. This axle is mounted for partial rotation in these bearings, and upon the spindles or` skeins thereof are mounted to revolve the wheels 18, which may be of any well-known or approved form of construction.

19 is a metallic bar the rear ends of which extend under and are secured to the side bars of the frame 4, the said bar, which constitutes a brace-bar, being diagonally extended across the bends at the forward ends of the side bars, as seen in Fig. 1, and being twisted, as at 20, to bring the forward portions in a vertical plane, and the said vertical portion is IOO Yss

bent around the forward end of the reach or coupling bar 7, as seen clearly at 21 in dotted lines in Fig. 1, suitable means being provided for securing the said bar to the reach, as seen in Figs. 1 and 2.

Secured to the front cross portions of the frame 4 is the bolster 22, from which rise the standards 23, between which is mounted the box 24, the forward end of which rests upon the front bolster 25 and between the standards 26, rising therefrom.

Secured to the upper face of the axle 17 is a plate 27, having rising centrally therefrom the vertical rib or portion 2S, the ends of said bar being bent parallel to form flanges 29, as seen best in Fig. 3, while upon the front face of the axle is the plate 30, the ends of which are bent at right angles to form the flanges 3l, as seen clearly in Fig. 4.

32 represents clamp-bars around the axle at the ends and bearing against the flanges 29 and 31 of the plates 27 and 30, as seen clearly in Figs. 3 and 4, so as to bind them rigidly in place. The lower ends of these clamps pass through openings in suitable plates 33 upon the under side of the axle and receive nuts 34, as seen clearly in Fig. 3.

35 represents clam p-plates having their upper portions bent to embrace the vertical web 28 of the plate 27 and having horizontal portions 36, which bear against the upper face of the horizontal portion of said plate, as seen clearly in Fig. 6, while the leg portions 37 embrace the rear face of the axle and the front face of the plate 30 and pass through openings in the plates 38, bearing against the under face of the axle, and receive the 'nuts 39, as seen clearly in Fig. 6. By these means I provide a very strong construction of axle and means for connecting the raketeeth, whereby injury to the parts is prevented as the machine passes over the sage-brush.

40 vrepresents the rake-teeth. They are made of sufficiently strong material to enable them to withstand the severe strain which they may be called upon to be subjected to, and they are fixed in position in the following manner: Each tooth has a shank passed through an opening 41 in the vertical portion or web 28 of the plate 27, and across the upper face of the horizontalportio of the plate 27 forwardgf .saidV web or portion 28, and thence "extended downward and bearing 1against the plate 30, being there secured by bolt or other suitable means 42,passed through the plate 30 and riveted upon the rear face thereof, as seen clearly in Fig. 4, whereby the teeth are held in a vertical as well as in a horizontal plane, making the connection most rigid Vand insuring against their displacement during the use of the machine. The shank of theseteeth may be in a plane above the level of the plate portion A27, as seen in Fig. 3, or they may rest upon said plate, as seen in Figs. 5 and 6. The raketeeth are disposed alternately with reference to the bars 14, as seen clearly in Fig. 1, so

that each tooth is in a plane between two of said bars, which latter serve as clearers for the teeth, as is common in this class of devices.

43 is an arm depending from the rear side ot' the axle 17 and having an offset portion 44, bearing against the upper face of the horizontal portions of the plate 27, and a vertical portion 45, having a bearing against the rear face of the web 28 thereof, as seen clearly in Fig. 5.

46 is a securing device having a vertical portion bearing against the front face of the plate 30, a lower horizontal portion 47, bearing against the under face of the axle, and an upper portion 48, which extends through the web 28 and through the vertical portion of the arm 43, where it is riveted or otherwise secured, as seen at 49 in Fig. 5. The other end of the member 46 passes through the arm 43, where it is riveted or otherwise Vafixed, as seen at 50 in said Fig. 5.

51 is a rod or bar having its lowermost and rear end connected, as at 52, to the lower portion of the arm 43 and-its other end extended forward along the side of the box 24 and pivotally connected, as at 53, with the lower end of the lever 54, fulcrumed, as at 55, and having a handle portion 56 and a spring-actuated bolt 57, adapted to engage any one of the notches 58 in the segment 59, secured to the side of the box and in the lowermost horizontal-connecting portion 60, on which the said lever is pivoted, all as seen most clearly in Fig. 2. This spring-actuated bolt isprovided `with a shank 6l, which is connected with the pivoted handle or lever 62, pivoted at 63 on the 1ever54, the spring 64, surrounding said shan k, being confined between suitable stops or cross portions 65, as seen clearly in said Fig. 2.

Mounted upon the rear end of the box 24 is a seedbox 66, in which is the usual spiral 67, carried by the shaft 68, one end of which shaft is extended and has a bearing in a suitable boxing or the like 69, supported in a suitable brace 73, secured to one of the side bars of the frame 4, and upon this extended end of the shaft is a pulley or band wheel 70, around which passesa belt 7l, which passes around a pulley 72, carried by the hub of the adjacent wheel 18, all as seen clearly in Figs. 1 and 2. These parts are so arranged that the spiral in the seedbox is actuated by the rotation of the Wheel 18 during the movement of the machine over the ground.

The operation will be apparent from the foregoing description when taken in connection with the annexed drawings, and a further detailed description thereof does not seein necessary.

Modifications in detail may be resorted to without departing from the spirit of the invention or sacrificing any of its advantages. What I claim as new isl. In a machine for grubbing sage-brush, a metallic frame having the rear portions of its IOO IIO
